BenchBuilt STM304 Insert is a precision-fit tool organizer designed to drop directly into the Ryobi LINK STM304 Compact Organizer case. No cutting, no modifications, no tools required — it simply drops in and locks your gear in place. Designed from actual STM304 interior measurements, this insert replaces the stock bins with a purpose-built layout: two upright drill bit sleeves, two chisel and driver bit channels, and a center tray for screws, bits, or small hardware. Everything has a home. Nothing slides. Printed in PETG for impact resistance, flexibility, and heat tolerance. Built to survive a real job site, a hot truck bed, and daily use — not just a desk drawer. Designed and made in the USA by BenchBuilt. IMPORTANT: This listing is for the BenchBuilt insert only. The Ryobi LINK STM304 case, tools, and drill bits shown are not included and are sold separately. BenchBuilt is not affiliated with, endorsed by, or sponsored by Ryobi or TTI.
